MeasureClassifFScore

mlr_measures_classif.f_score

Calls <code><a rd-options="Metrics:fbeta_score" href="/link/Metrics%3A%3Afbeta_score()?package=mlr3&version=0.1.4&to=Metrics%3Afbeta_score" data-mini-rdoc="Metrics:fbeta_score::Metrics::fbeta_score()">Metrics::fbeta_score()</a></code>.
Argument <code>beta</code> defaults to <code>1</code>.

datasets

Efficient, object-oriented programming on the building blocks of
machine learning. Provides 'R6' objects for tasks, learners, resamplings,
and measures. The package is geared towards scalability and larger datasets
by supporting parallelization and out-of-memory data-backends like
databases. While 'mlr3' focuses on the core computational operations,
add-on packages provide additional functionality.
